that eating wild salmon can help to eliminate wrinkles, restore radiance, and even out skin tone? Its bright red or pink pigment is from astaxanthin, an antioxidant that enables the skin to repair damaged collagen, resulting in smoother, more youthful skin. —Dr. Nicholas Perricone

that in skin with acne, an overproduction of cells leads to a layer of “dead” cells that combines with the skin’s own natural oil, resulting in acne?

that the difference you observe between the two people you know who are the same age and look years apart is due to the sun? Sunscreen is not overrated. Once you protect yourself from the sun you need to have a good skin-care regimen, and you need to start young. Using exfoliation when you are young works on pimples and when you are older it helps you obtain a radiant glow; so no matter what age, it always has a purpose. —Dr. Patricia Wexler
